end of the drum. The opposite end of tee drum is'provided with a web portion 108 I that terminates in a widened friction rim 109. 110 represents a pinion journaled upon the other hub member at the opposite end of the drum, and including a'flange memher 111, having transverse bolt receiving openings 112 therein that register with corresponding openings in the flange portion 108 of the drum, whereby the pinion may be connected with the drum The pinion 110 meshes with the gear .wheel 95 and turns loosely upon the hub-of the drum when the gear wheel 105 is secured to the opposite end of the drum. The pinion 39 and the gear wheel 95 are speed reducing gears between the gear 32 and the sleeve 97,

and the pinion 98 andgear wheel 105 are speed reducing gears between the sleeve 97 and the drum 102 when the gear wheel 105 is secured to the drum; therefore, "when the set screws 117, as shown in Fig. 12.

Integral v with the pinion 113 is a friction rim 119 that -shaft having its opposite ends secured in is adapted to engage with a friction wheel 1 120 carried by the opposite end of the rock shaft 118, and including a body member 121 that rotates freely between outside and inbracket member 115; the opposite plate 122 being-secured to the shaft 118 by means of the screw 125. The body member 121 is provided with an axial opening that'receives a bushing 126, and 127 represents an eccentric sleeve secured to the shaft 118 and operative tomove the friction wheel bodily toward or from the friction rim 119, carried by the pinion 113 and the friction rim 109 of the drum 102. The pinion';113 meshes with the gear and is given constantrotation.

128 represents a line guiding roller journaled upon the rock shaft 118, and 129 a supplemental line guiding roller journaled upon a. vertically disposed stud 130 carried by a bracket 131 secured to opposite sides of the transverse frame member-"116 by means of r the same bolts that secure'the bracket memin a flange 107 integral with theadpcent her 115. The shaftllS may be'rocked in its bearings by means including a hand lever 132,11av1ng its lower end secured to a sleeve member 133 journaledunon the shaft 51 and provided with an inwardly extendingarm 131 that is connected, by means ofa link 135, with an arm 136 integral with a sleeve mem ber 137secured to the shaft 118, as by means of a set screw 138, the associated parts of the mechanism. being so arranged thatwhen the hand lever 132 is moved outward the friction wheel 120 engages with the friction rim 119 below and in front of the drum 102, and 1 10 represents vertically disposed line guiding rollers that are journaled upon shafts 141 that are loosely received by any 'of a series of several shafts,

mounted thereon, may be readily removed where it will be mostly used.
